An expression used when an associate (most commonly a suspicious girl friend or wife), has been seriously contemplating your possible (likely) infidelity or unfaithfulness. This expression usually is in reference to your whereabouts within the previous 24 hours, before the gf/wife has been able to make any real discoveries. This, leaving her at this point, just wonderinâ.

You: I cane home.
Girlfriend: No, I mean before you cane home?
You: I did a few things, why, whatâs with all the detective work?
Girlfriend: Oh, just wonderinâ.
